Border (ボーダー Bōdā?) is an agency in Mikado City. It was created for the sake of protecting the city from Neighbor attacks. They fight the Neighbors by the means of triggers, the technology used by Neighbors.
Main Article: Old Border
Before it became publicly known, Border was a secret organization with the purpose of being an intermediary between ‘Earth’ and Neighbors. Along with its establishment, Border has made an alliance with three Neighbor nations, Aristera, Meson, and Dexio, and used the building that later became Tamakoma's base as its headquarters.
Between its establishment and 6 years before the start of the series, Border had 19 people within its ranks. However, about a year later, an allied nation was invaded by a hostile nation and when Borders sent its forces to assist, 10 out of 19 died, with some becoming Black Triggers. After the incident, the organization split into two, one became the current Headquarters and the other became Tamakoma Branch.
About four and a half years before the start of the series, Border made its first public appearance when the First Large-Scale Invasion occurred. Soon after that, Border built its Headquarters in the middle of an area known as the Danger Zone and began recruiting new members.
The management supervises all Border employees and the safety of Mikado City from Neighbor-related threats. They are also involved in tasks such as P.R., a gathering of funds, and supervision of the R&D Department, as well as in the organization of away expeditions. engineers are in charge of everything all matters technology, while operators provide intelligence to agents and serve as their connection to HQ. Agents fight trion soldiers and similar threats. However, they are not always at the scene in time, leaving citizens to fend for themselves or if there's an agent, to fight it themselves. Some agents are also involved in P.R. initiatives and recruiting. A-class and B-class members are paid, but C-class trainees are not, as they are not official agents and are not supposed to engage in combat outside of training. However, they have recently received clearance to activate their triggers to help with evacuation and rescue during emergencies.
There are four ranks available to Border agents. These ranks do not constitute an actual hierarchy, but express the status of an agent and their team within Border: C-rank is for trainees, A and B-rank are for official agents with normal Triggers, and S-rank is for official agents wielding Black Triggers.
New agents start from C-rank. When they reach 4000 usage points with their Training Trigger, they are promoted to B-rank and allowed to form a unit. To advance to A-rank, the unit must perform well in rank wars, meaning it is not the individual who is promoted, but the team as a whole. Agents who wield Black Triggers are immediately categorized as S-rank and do not participate in rank battles. In general, only A-rank agents are sent to the Neighborhood, but there are exceptions.
Border uses a point system to track agents' skills with their Trigger or Trigger set. C-Class trainee agents start from 1000 points, but they are given extra points if they have performed well in the preliminary tests. Points can be earned by winning optional rank battles against other trainees, while losses result in a deduction of points. The greater the point gap, the fewer points are awarded to the winner if they had a large advantage in points; vice versa, if they lose in the same conditions, they will lose more points than normal: when someone with 1100 points defeated an opponent with 2358, he took 225 points from him. Cadets can also fight official agents, but the scores of the two contestants will not be altered at the end of the match.
Attacker, Gunner and Shooter trainees can also score points in group training sessions that take place twice a week. There are five drills, only three of which are known: Topography Traversal Training, Covert Action Training, and Detection and Tracking Training. Sniper trainees, on the other hand, receive points base don their performance during joint Sniper training. A perfect score awards 20 points, for a maximum of 200 points per week. During the most recent enlistment session, all cadets started with 1000 points and took part in four five-way matches, due to the session has taken place at an irregular date, with no time for a probationary period. Extra points can also be given out by the management as special awards. Individual points determine an agent's Solo Ranking (how they stack up in comparison to all other official agents) as well as their Position Ranking (how they stack up in comparison to all other official agents with their own position).
When a cadet reaches 4000 points with their Trigger, they are promoted to B-rank. Sniper cadets can also be promoted if they manage to make the top 15% for three weeks in a row. An agent's points correspond to their highest score with anyone Trigger in their possession. Dropping below 4000 points with all of one's Triggers does not result in the demotion from official agent to the trainee, which is however the case if the score of any one of the agent's Triggers drops below 1500, but this has never occurred thus far. An agent who reaches 8000 points with anyone Trigger is said to have reached Master Class with it. Official agents adding a new Trigger to their set will start from 3000 points, 4000 if they are Master Class. In rank battles, if an agent fights with two Triggers, the one which dealt the final blow receives 70% of the total score, the other one 30%.

According to Jin, there are roughly three unofficial ideological factions within Border.
|Kido Faction||Shinoda Faction||Tamakoma Branch|
|"Never forgive Neighbors" (近界民は絶対許さないぞ主義 Neibā wa zettai yurusanai zo shugi?)||"The safety of the town is first and foremost" (町の平和が第一だよね主義 Machi no heiwa ga daiichi da yo ne shugi?)||"There are good Neighbors, so let's be friends!" (近界民にもいいヤツいるからなかよくしようぜ主義 Neibā ni mo ii yatsu iru kara nakayoku shiyō ze shugi?)|
Not all units fall into these factions, such as Nasu Unit and Kageura Unit. However everyone who is in a faction directly responds to their faction leader and do not have to follow the other leaders orders like what Yūichi Jin did in Chapter 17
The core of Border's operations is a massive fortress with trion cannons and reinforced walls. Aside from offices, common areas, and other ordinary spaces, it contains laboratories for the engineers, control rooms for Operators, private rooms for official units, and virtual spaces for agents to train in. Deep underground is also a vessel made out of trion to travel to the Neighborhood. Around the headquarters is an unhinabited, devastated portion of Mikado City where Gates are redirected, so they open away from ordinary citizens. However, this technology cannot prevent rads from opening portals elsewhere.
There are 6 branches in Border. Personnel that are not aiming for A-rank are associated with a branch. They are placed on the outside of the danger zone, and act as a contact point for locals.
- In the Viz version, it was called Border Defense Agency, which is also in Border's logo.
- The uniforms of current Border agents are different from those of Old Border members due to the engineers increasing in number.
- Border agents are split between those who constantly use a trion body at HQ and those who don’t. The former are rumored to have problems sleeping due to their flesh and blood bodies not getting tired.
